Prevention of postoperative pulmonary complications through intensive preoperative respiratory rehabilitation in patients with esophageal cancer

What is the role of physical exercise in the era of cancer prehabilitation? A systematic review

PURPOSE

Exercise before surgery, as part of prehabilitation, aiming to enhance patients' functional and physiological capacity, has become widespread, necessitating an in-depth understanding.

METHODS

A systematic search was conducted on Pubmed, Cochrane, and Scopus to examine the effect of exercise as prehabilitation, alone or in combination with other interventions, in patients with cancer. Interventional studies applying a single-arm, randomized controlled, or nonrandomized design were included.

RESULTS

A total of 96 studies were included, and categorized according to cancer types, i.e., gynecological, breast, urological, gastrointestinal and lung cancer. For each cancer site, the effect of exercise, on physical fitness parameters and postoperative outcomes, including length of hospital stay and postoperative complications, was reported.

CONCLUSION

Exercise as prehabilitation may have an important role in improving physical fitness, postoperative outcomes, and accelerating recovery, especially in certain types of malignancies.

Towards a common definition of surgical prehabilitation: a scoping review of randomised trials

BACKGROUND

There is no universally accepted definition for surgical prehabilitation. The objectives of this scoping review were to (1) identify how surgical prehabilitation is defined across randomised controlled trials and (2) propose a common definition.

METHODS

The final search was conducted in February 2023 using MEDLINE, Embase, PsycINFO, Web of Science, CINAHL, and Cochrane. We included randomised controlled trials (RCTs) of unimodal or multimodal prehabilitation interventions (nutrition, exercise, and psychological support) lasting at least 7 days in adults undergoing elective surgery. Qualitative data were analysed using summative content analysis.

RESULTS

We identified 76 prehabilitation trials of patients undergoing abdominal (n=26, 34%), orthopaedic (n=20, 26%), thoracic (n=14, 18%), cardiac (n=7, 9%), spinal (n=4, 5%), and other (n=5, 7%) surgeries. Surgical prehabilitation was explicitly defined in more than half of these RCTs (n=42, 55%). Our findings consolidated the following definition: 'Prehabilitation is a process from diagnosis to surgery, consisting of one or more preoperative interventions of exercise, nutrition, psychological strategies and respiratory training, that aims to enhance functional capacity and physiological reserve to allow patients to withstand surgical stressors, improve postoperative outcomes, and facilitate recovery.'

CONCLUSIONS

A common definition is the first step towards standardisation, which is needed to guide future high-quality research and advance the field of prehabilitation. The proposed definition should be further evaluated by international stakeholders to ensure that it is comprehensive and globally accepted.

Detrimental impact of late-onset pneumonia on long-term prognosis in oesophageal cancer survivors

BACKGROUD

Oesophageal cancer patients are prone to early- and late-onset pneumonia after oesophagectomy. We aimed to investigate the incidence rate and impact on the long-term prognosis of late-onset pneumonia in oesophageal cancer survivors who survived for at least one year after oesophagectomy without cancer recurrence.

METHODS

We retrospectively reviewed 233 patients with thoracic oesophageal cancer who underwent oesophagectomy with gastric conduit reconstruction between September 2009 and June 2019 at a tertiary referral hospital in Japan. Pneumonia that occurred ≥1 year after oesophagectomy was defined as late-onset pneumonia.

RESULTS

Among the 185 oesophageal cancer survivors, 31 (17%) developed late-onset pneumonia. The cumulative incidence rates of late-onset pneumonia 24, 36, and 60 months after oesophagectomy were 6.4%, 10%, and 21%, respectively, whereas pneumonia recurred at 21%, 31%, and 52% within 6, 12, and 24 months, respectively, after the first pneumonia. Chronic obstructive pulmonary disease, postoperative anastomotic leakage, and loss of skeletal muscle mass were independently associated with late-onset pneumonia, and a combination of these factors further increased the risk. Late-onset pneumonia with hospitalisation had the greatest negative impact on the long-term prognosis as non-cancer deaths (HR, 21; p < 0.001), followed by recurrent late-onset pneumonia (HR, 18; p < 0.001).

CONCLUSIONS

Late-onset pneumonia in oesophageal cancer survivors is significantly associated with an increased risk of recurrent infections and non-cancer deaths. Chronic obstructive pulmonary disease and postoperative muscle loss are risk factors for late-onset pneumonia, and more intensive pharmacological and nutritional interventions should be considered to improve long-term prognosis after oesophagectomy.

A Combat Journey of Rehabilitation in Pre- and Post-chemotherapy for Esophagus Carcinoma

Esophageal cancer is a malignant epithelial alteration that takes place in the middle or upper part of the esophagus. Given the escalating population of individuals who have successfully overcome esophageal cancer, the significance of addressing disease- and treatment-associated complaints and symptoms is increasingly pertinent. This highlights the necessity of interventions meant to enhance quality of life (QOL). We present the case of a 60-year-old female diagnosed with esophageal squamous cell carcinoma who presented with chief complaints of generalized weakness, breathlessness, and nausea. Patient-tailored physiotherapy pre-rehabilitation and post-rehabilitation, including strengthening exercises, breathing exercises, dyspnea-relieving positions, Mendelsohn maneuver, Shaker exercise, among others, were administered. These interventions proved effective in enhancing the patient's functional independence and QOL. Treatment commenced one week prior to the first chemotherapy session. Post-chemotherapy intervention was provided, and on the day of discharge, follow-up revealed improved strength and QOL.

Preoperative DLco and FEV1 are correlated with postoperative pulmonary complications in patients after esophagectomy

Limited information is available regarding the association between preoperative lung function and postoperative pulmonary complications (PPCs) in patients with esophageal cancer who undergo esophagectomy. This is a retrospective cohort study. Patients were classified into low and high lung function groups by the cutoff of the lowest fifth quintile of forced expiratory volume in 1 s (FEV1) %predicted (%pred) and diffusing capacity of the carbon monoxide (DLco) %pred. The PPCs compromised of atelectasis requiring bronchoscopic intervention, pneumonia, and acute lung injury/acute respiratory distress syndrome. Modified multivariable-adjusted Poisson regression model using robust error variances and inverse probability treatment weighting (IPTW) were used to assess the relative risk (RR) for the PPCs. A joint effect model considered FEV1%pred and DLco %pred together for the estimation of RR for the PPCs. Of 810 patients with esophageal cancer who underwent esophagectomy, 159 (19.6%) developed PPCs. The adjusted RR for PPCs in the low FEV1 group relative to high FEV1 group was 1.48 (95% confidence interval [CI] = 1.09-2.00) and 1.98 (95% CI = 1.46-2.68) in the low DLco group relative to the high DLco group. A joint effect model showed adjusted RR of PPCs was highest in patients with low DLco and low FEV1 followed by low DLco and high FEV1, high DLco and low FEV1, and high DLco and high FEV1 (Reference). Results were consistent with the IPTW. Reduced preoperative lung function (FEV1 and DLco) is associated with post-esophagectomy PPCs. The risk was further strengthened when both values decreased together.

Does prehabilitation before esophagectomy improve postoperative outcomes? A systematic review and meta-analysis

Esophagectomy for esophageal cancer is associated with high morbidity. It remains unclear whether prehabilitation, a strategy aimed at optimizing patients' physical and mental functioning prior to surgery, improves postoperative outcomes. A systematic review and meta-analysis was conducted to evaluate the effect of prehabilitation on post-operative outcomes after esophagectomy. Data sources included Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, and PEDro, with information from 1 January 2000 to 5 August 2023. The analysis included randomized controlled trials and observational studies that compared prehabilitation interventions to standard care prior to esophagectomy. A random effects model was used to generate a pooled estimate for pairwise meta-analysis, meta-analysis of proportions, and meta-analysis of means. A total of 1803 patients were included with 584 in randomized controlled trials (RCTs) and 1219 in observational studies. In the randomized evidence, there were no significant differences between prehabilitation and control in the odds of postoperative pneumonia (15.0 vs. 18.9%, odds ratio (OR) 1.06 [95% confidence interval (CI): 0.66;1.72]) or pulmonary complications (14 vs. 25.6%, OR 0.68 [95% CI: 0.32;1.45]). In the observational data, there was a reduction in both postoperative pneumonia (22.5 vs. 32.9%, OR 0.48 [95% CI: 0.28;0.83]) and pulmonary complications (26.1 vs. 52.3%, OR 0.35 [95% CI: 0.17;0.75]) with prehabilitation. Hospital and intensive care unit length of stay (days), operative mortality, and severe complications (Clavien-Dindo ≥ 3) did not differ between groups in both the randomized data and observational data. Prehabilitation demonstrated reductions in postoperative pneumonia and pulmonary complications in observational studies, but not RCTs. The overall certainty of these findings is limited by the low quality of the available evidence.

Preoperative physical activity is associated with prognosis in patients with esophageal cancer undergoing thoracoscopic-laparoscopic esophagectomy after neoadjuvant chemotherapy

OBJECTIVE

This study examined the association between a single preoperative physiotherapy session during neoadjuvant chemotherapy and physical function and that between preoperative physical activity and prognosis.

METHODS

In this retrospective, single-center, observational study, we evaluated data from 234 patients scheduled for neoadjuvant chemotherapy and thoracoscopic-laparoscopic esophagectomy who underwent a single preoperative physiotherapy session. The five-repetition sit-to-stand test was performed before and after neoadjuvant chemotherapy. After neoadjuvant chemotherapy, patients were classified into high- and low-physical activity groups based on preoperative physical activity. To examine the association between preoperative physiotherapy and changes in physical function, a multivariate regression analysis was performed. The Cox proportional hazards model was used to investigate the association between preoperative physical activity and overall survival.

RESULTS

The median percentage change in the five-repetition sit-to-stand test score was - 3.36%. In the multivariate regression analysis, the regression coefficient of the constant term was - 23.93 (95% confidence interval - 45.31 to - 2.56; P = 0.028). Low physical activity was significantly associated with overall survival after adjustment for confounding factors (P = 0.040).

CONCLUSIONS

This study demonstrated that a single preoperative physiotherapy session during neoadjuvant chemotherapy improves physical function, and preoperative physical activity is significantly associated with prognosis.

Effects of unimodal or multimodal prehabilitation on patients undergoing surgery for esophagogastric cancer: a systematic review and meta-analysis

PURPOSE

To evaluate the effects of unimodal or multimodal prehabilitation on patients undergoing surgery for esophagogastric cancer.

METHODS

We conducted a systematic search of the PubMed, Embase, CINAHL, Web of Science, and Cochrane Library (CENTRAL) databases from database inception to May 5, 2023, for randomized controlled trials (RCTs) and cohort studies that investigated prehabilitation in the context of esophagogastric cancer. A random-effects model was used for meta-analysis.

RESULTS

We identified 2,994 records and eventually included 12 studies (6 RCTs and 6 cohort studies) with a total of 910 patients. According to random-effects pooled estimates, prehabilitation reduced the incidence of all complications (RR = 0.79, 95% CI: 0.66 to 0.93, P = 0.006), pulmonary complications (RR = 0.61, 95% CI: 0.47 to 0.79, P = 0.0002), and severe complications (RR = 0.63, 95% CI: 0.47 to 0.84, P = 0.002), and shortened the length of stay (MD = -1.92, 95% CI: -3.11 to -0.73, P = 0.002) compared to usual care. However, there were no statistically significant differences in 30-day readmission rates or in-hospital mortality. Subgroup analysis showed that multimodal prehabilitation was effective in reducing the risk of all complications and severe complications, while unimodal prehabilitation was not.

CONCLUSIONS

Our findings suggested that prehabilitation may be beneficial in reducing postoperative complications and length of stay. We recommend preoperative prehabilitation to improve postoperative outcomes and hasten recovery following esophagogastric cancer surgery, and multimodal prehabilitation seems to be more advantageous in reducing complications. However, further studies are needed to confirm these results.

Safety and Feasibility of Mediastinoscopy-assisted Esophagectomy: A Meta-analysis

BACKGROUND

The objective of the current study was to investigate the safety and feasibility of mediastinoscopy-assisted esophagectomy (MAE).

METHODS

A meta-analysis was conducted between MAE and traditional transthoracic esophagectomy (TTE). For a comparative analysis of MAE and TTE, we searched PubMed, the Cochrane Library, Embase, and Web of Science databases. We identified the relevant literature and extracted the relevant data. Finally, RevMan 5.3 software was applied to conduct a meta-analysis of the data.

RESULTS

A total of 1256 people were enrolled in 16 studies, comprising 575 patients with MAE and 681 with TTE. The findings revealed that the pulmonary complications, cardiac complications, and postoperative hospital stay in the MAE group were significantly better than those in the TTE group. No significant differences were found between the 2 groups in postoperative chylothorax, anastomotic fistula, and postoperative mortality. But the incidence of recurrent laryngeal nerve injury in the MAE group was higher than that in the TTE group (odds ratio=1.64, 95% CI, 1.15 to 2.35, P =0.006). The MAE group had less lymph node dissection than the TTE group (mean difference=-4.62, 95% CI, -5.97 to 3.45, P <0.00001).

CONCLUSIONS

This meta-analysis presented that MAE was safe and feasible, reduced postoperative pulmonary and cardiac complications, and shortened hospital stay, but lymph node dissection was less, recurrent laryngeal nerve injury was higher, and the impact of long-term survival prognosis required more randomized controlled trials.

Effect of Three Weeks of High-Intensity, Long-Term Preoperative Rehabilitation for Esophageal Cancer Patients with Stroke Sequelae Who Were Considered Unfit for Surgery Due to Low Activity: A Case Report

Treatment of esophageal cancer is based on tumor-node-metastasis (TNM) classification, and surgical treatment is chosen based on the patient's ability to tolerate surgery. Surgical endurance partly depends on activity status, with performance status (PS) generally used as an indicator. This report describes a 72-year-old man with lower esophageal cancer and an 8-year history of severe left hemiplegia. He had sequelae of cerebral infarction and a TNM classification of T3, N1, and M0, and was judged ineligible for surgery because his PS was grade three; he underwent preoperative rehabilitation with hospitalization for 3 weeks. He had been able to walk with a cane in the past, but once he was diagnosed with esophageal cancer, he began using a wheelchair and was dependent on assistance from his family in his daily life. Rehabilitation consisted of strength training, aerobic exercise, gait training, and activities of daily living (ADL) training for 5 h a day, according to the patient's condition. After 3 weeks of rehabilitation, his ADL ability and PS improved sufficiently for surgical indication. No complications occurred postoperatively, and he was discharged when his ADL ability was higher than that before preoperative rehabilitation. This case provides valuable information for the rehabilitation of patients with inactive esophageal cancer.

Effects of body composition on early postoperative discharge and postoperative complications in patients with esophageal cancer

BACKGROUND

Patients with esophageal cancer are prone to nutrition deterioration during the perioperative period and have a high incidence of postoperative complications, prolonging hospitalization. Decreased muscle mass is a known contributor to this deterioration, but there is insufficient evidence on the effects of preoperative maintenance and improvement of muscle mass. In this study, we evaluated the relationship between body composition, early postoperative discharge, and postoperative complications in patients with esophageal cancer.

METHODS

This was a retrospective cohort study. Patients were divided into an early discharge group and a control group, who were discharged ≤21 days postoperatively and >21 days, respectively. The relationship of body composition to postoperative complications and discharge time in patients was evaluated via multivariate logistic regression using isotemporal substitution (IS) models.

RESULTS

The early discharge group comprised 31 of the 117 patients (26%) included. This group had significantly lower incidences of sarcopenia and postoperative complications than the control group. In logistic regression analyses estimating the effect of changes in body composition using the IS models, preoperative replacement of 1 kg of body fat with 1 kg of muscle mass was associated with significantly higher odds of early discharge (odds ratio [OR], 1.28; 95% CI, 1.03-1.59) and lower odds of postoperative complications (OR, 0.81; 95% CI, 0.66-0.98).

CONCLUSION

In patients with esophageal cancer, a preoperative increase in muscle mass may reduce postoperative complications and hospital stay duration.

Osteopenia Is Associated with Shorter Survival in Patients with Intrahepatic Cholangiocarcinoma

BACKGROUND

The prognostic importance of osteopenia in patients with intrahepatic cholangiocarcinoma (ICC) undergoing hepatectomy is unclear. The aim of this study was to evaluate the impact of osteopenia on survival in patients with ICC.

METHODS

A total of 71 patients who underwent hepatectomy at Jichi Medical University between July 2008 and June 2022 were included in this study. Non-contrast computed tomography scan images at the eleventh thoracic vertebra were used to assess bone mineral density. The cutoff value was calculated using a threshold value of 160 Hounsfield units. Overall survival curves were made using the Kaplan-Meier method and the log-rank test was used to evaluate survival. The hazard ratio (HR) and 95% confidence interval (CI) for overall survival were calculated using Cox's proportional hazard model.

RESULTS

In multivariable analysis, osteopenia (HR 3.66, 95%CI 1.16-14.1, p = 0.0258) and the platelet-lymphocyte ratio (HR 6.26, 95%CI 2.27-15.9, p = 0.0008) were significant independent factors associated with overall survival. There were no significant independent prognostic factors for recurrence-free survival.

CONCLUSIONS

Preoperative osteopenia is significantly associated with postoperative survival in patients with ICC undergoing hepatectomy.

Evaluation of sarcopenia and sarcopenic obesity in patients affected by oral squamous cell carcinoma: A retrospective single-center study

This retrospective single-center study aimed to evaluate the relevance of sarcopenia and sarcopenic obesity as negative prognostic factors in patients with oral squamous cell carcinoma (OSCC). The study was performed on patients who underwent oral squamous cell carcinoma resection surgery. Patients' demographic and clinical variables were collected at diagnosis (sex, age, height, weight, comorbidities, smoke and alcohol consumption, HPV positivity, TNM-stage) and corrected for known prognostic factors (age, body mass index, TNM-stage). The Skeletal Muscle Mass (SMM) and the Cross-Sectional Area (CSA) on pre-treatment CT scans and Body Mass Index (BMI) were measured to assess sarcopenia and sarcopenic obesity correlated to overall survival (OS). Chi-square statistics were used to analyze the differences between the frequencies of each categorical variable with the presence or absence of sarcopenia and sarcopenic obesity. The cumulative overall survival was calculated by the Kaplan-Meier method, and the differences between curves were evaluated by the log-rank test. A Cox proportional hazard regression model was used for univariate and multivariate analysis of the overall survival. Within the limitations of the study, in this sample, sarcopenia did not seem to cause a statistically significant reduction in the overall survival in patients with oral squamous cell carcinoma (Log Rank χ2 = 3.67, p = 0.055; HR 0.996, 95% CI 0.732-1.354, p = 0.979), however, sarcopenic obesity showed a meaningful negative prognostic impact on it (Log Rank χ2 = 5.71, p = 0.017; HR 0.985, 95% CI 0.424-2.286, p = 0.972). Within the limitations of the study it seems that sarcopenic obesity, age, BMI, and TNM-stage are more relevant negative prognostic factors, influencing overall survival in surgically treated OSCC, than sarcopenia.

Effect of a multimodal prehabilitation program on postoperative recovery and morbidity in patients undergoing a totally minimally invasive esophagectomy

Postoperative morbidity following esophagectomy remains substantial. Studies in major abdominal surgery have shown that prehabilitation can improve postoperative outcomes. This single-center study investigated the influence of prehabilitation on postoperative outcomes in patients undergoing minimally invasive Ivor-Lewis esophagectomy (MIE-IL). Data were collected on patients that underwent a MIE-IL and received a fully standardized enhanced recovery after surgery (ERAS) program, between October 2015 and February 2020. The intervention group comprised patients enrolled in the PREPARE prehabilitation program. The control group comprised a retrospective cohort with similar ERAS care, prior to implementation of PREPARE. Postoperative outcomes included (functional) recovery, length of hospital stay (LOHS), cardiopulmonary complications (CPC) and other predefined outcomes. The PREPARE group comprised 52 and control group 43 patients. Median time to functional recovery was 6 vs. 7 days (P = 0.074) and LOHS 7 vs. 8 days (P = 0.039) in PREPARE and control patients, respectively. Hospital readmission rate was 9.6 vs. 14.3% (P = 0.484). A 17% reduction in thirty-day overall postoperative complication rate was observed in PREPARE patients, but this was not statistically significant (P = 0.106). Similarly, a clinically relevant reduction of 14% in CPC rate was observed (P = 0.190). Anastomotic leakage rate was similar (9.6 vs 14.0%; P = 0.511). Despite no difference in severity (Clavien-Dindo) of complications (P = 0.311), ICU readmission rate was lower in PREPARE patients (3.8 vs. 16.3%, P = 0.039). Prehabilitation prior to MIE-IL led to a shorter LOHS and reduced ICU readmission rate. Additionally, a clinically relevant improvement in postoperative recovery and reduced morbidity rate was observed in prehabilitated patient.

Difference between “Lung Age” and Real Age as a Novel Predictor of Postoperative Complications, Long-Term Survival for Patients with Esophageal Cancer after Minimally Invasive Esophagectomy

Background

This study aimed to investigate whether the difference between “lung age” and real age (L–R) could be useful for the prediction of postoperative complications and long-term survival in patients with esophageal cancer followed by minimally invasive esophagectomy (MIE).

Methods

This retrospective cohort study included 625 consecutive patients who had undergone MIE. “Lung age” was determined by the calculation method proposed by the Japanese Respiratory Society. According to L–R, patients were classified into three groups: group A: L–R ≦ 0 (n = 104), group B: 15 > L–R > 0 (n = 199), group C: L–R ≥ 15 (n = 322). Clinicopathological factors, postoperative complications evaluated by comprehensive complications index (CCI), and overall survival were compared between the groups. A CCI value >30 indicated a severe postoperative complication.

Results

Male, smoking status, smoking index, chronic obstructive pulmonary disease, American Society of Anesthesiologists status, lung age, and forced expiratory volume in 1 s were associated with group classification. CCI values, postoperative hospital stays, and hospital costs were significantly different among groups. Multivariate analysis indicated that L–R, coronary heart disease, and 3-field lymphadenectomy were significant factors for predicting CCI value >30. Regarding the prediction of CCI value >30, area under the curve value was 0.61(95%: 0.56–0.67), 0.46 (95% CI, 0.40–0.54), and 0.46 (95% CI, 0.40–0.54) for L–R, Fev1, and Fev1%, respectively. Regarding overall survival, there was a significant difference between group A and group B + C (log-rank test: p = 0.03).

Conclusions

Esophageal cancer patients with impaired pulmonary function had a higher risk of severe postoperative complications and poorer prognosis than those with normal pulmonary function. The difference between “lung age” and “real age” seems to be a novel and potential predictor of severe postoperative complications and long-term survival.

Physiotherapy Regimens in Esophagectomy and Gastrectomy: a Systematic Review and Meta-Analysis

Background

Esophageal and gastric cancer surgery are associated with considerable morbidity, specifically postoperative pulmonary complications (PPCs), potentially accentuated by underlying challenges with malnutrition and cachexia affecting respiratory muscle mass. Physiotherapy regimens aim to increase the respiratory muscle strength and may prevent postoperative morbidity.

Objective

The aim of this study was to assess the impact of physiotherapy regimens in patients treated with esophagectomy or gastrectomy.

Methods

An electronic database search was performed in the MEDLINE, EMBASE, CENTRAL, CINAHL and Pedro databases. A meta-analysis was performed to assess the impact of physiotherapy on the functional capacity, incidence of PPCs and postoperative morbidity, in-hospital mortality rate, length of hospital stay (LOS) and health-related quality of life (HRQoL).

Results

Seven randomized controlled trials (RCTs) and seven cohort studies assessing prehabilitation totaling 960 patients, and five RCTs and five cohort studies assessing peri- or postoperative physiotherapy with 703 total patients, were included. Prehabilitation resulted in a lower incidence of postoperative pneumonia and morbidity (Clavien–Dindo score ≥ II). No difference was observed in functional exercise capacity and in-hospital mortality following prehabilitation. Meanwhile, peri- or postoperative rehabilitation resulted in a lower incidence of pneumonia, shorter LOS, and better HRQoL scores for dyspnea and physical functioning, while no differences were found for the QoL summary score, global health status, fatigue, and pain scores.

Conclusion

This meta-analysis suggests that implementing an exercise intervention may be beneficial in both the preoperative and peri- or postoperative periods. Further investigation is needed to understand the mechanism through which exercise interventions improve clinical outcomes and which patient subgroup will gain the maximal benefit.

Impairment of Lung Function Increases the Risk of Postoperative Respiratory Failure for Esophageal Carcinoma: A Systematic Review and Meta-Analysis

Objective

To study lung function impairment by meta-analysis to increase the risk of postoperative respiratory failure in patients with esophageal carcinoma.

Methods

We searched PubMed, ScienceDirect, and CNKI and other databases, and the search time was set to the time the database was established. We screened the relevant literature to study the relationship between lung function damage and postoperative respiratory failure in patients with esophageal cancer, determined to include the literature and extracted relevant data, and then, applied NOS. The scale evaluates the quality of the literature, and the ReviewManager software was used to perform meta-analysis on the extracted data.

Results

Finally, 9 related articles and 2822 research subjects were included, and the average score of literature quality was 5.78 points, the heterogeneity of the literature was large (I² = 84%), the random effects model was used for analysis, and the correlation between the two showed SMD = 0.09, 95%CI[−0.09, 0.31], Z = 1.10, P = 0.27, which is consistent with the results of the subgroup analysis.

Conclusion

The results of the study show that lung function impairment has a positive relationship with postoperative respiratory failure in patients with esophageal cancer. Pulmonary function impairment in cases with different case characteristics can also aggravate the severity of respiratory failure.

Salvage minimally invasive esophagectomy after definitive chemoradiotherapy for esophageal cancer can improve postoperative complications compared with salvage open esophagectomy

BACKGROUND

Although the advantage of minimally invasive esophagectomy (MIE) over open esophagectomy (OE) in planned esophagectomy is being established, the utility of salvage MIE (S-MIE) remains unclear. We aimed to investigate the feasibility and advantage of S-MIE compared with salvage OE (S-OE).

METHODS

We retrospectively assessed 82 patients who underwent salvage esophagectomy after definitive chemoradiotherapy for thoracic esophageal cancer between January 2007 and April 2020. Perioperative factors and postoperative complications were compared between the S-OE group (n = 62) and the S-MIE group (n = 20). Logistic regression analysis was performed to analyze the factors associated with postoperative complications.

RESULTS

Regarding the patients' preoperative characteristics, the S-OE group had a significant number of grade ≥ cT3 patients vs the S-MIE group (69% vs 35%, respectively; p = 0.006), whereas ycT rates were comparable. Compared with S-OE, S-MIE had comparable operative time, number of harvested thoracic lymph nodes, and R0 resection, but significantly less estimated blood loss (150 ml and 395 ml, respectively; p = 0.003). Regarding postoperative complications, total complications (79% vs 50%; p = 0.01) and pneumonia (48.3% vs 20%; p = 0.02) rates were significantly lower with S-OE vs S-MIE, respectively. On multivariate analysis, S-MIE was an independent factor associated with postoperative pneumonia (odds ratio: 0.29, 95% confidence interval: 0.06-0.99; p = 0.04) and total complications (odds ratio: 0.26, 95% confidence interval: 0.07-0.86; p = 0.02).

CONCLUSION

S-MIE was feasible for salvage esophagectomy, with favorable short-term outcomes vs S-OE regarding postoperative pneumonia and total complications.

What are the impact and the optimal design of a physical prehabilitation program in patients with esophagogastric cancer awaiting surgery? A systematic review

Background

Substantial postoperative complications occur after tumor resection for esophagogastric cancers. Physical prehabilitation programs aim to prepare patients for surgery by improving their functional status with the aim of reducing postoperative complications. This systematic review aims to summarize the effects of physical prehabilitation programs on exercise capacity, muscle strength, respiratory muscle function, postoperative outcomes, and health-related quality of life and to determine the optimal design of such a program to improve these outcomes in esophagogastric cancer patients undergoing tumor resection.

Methods

A systematic literature review was conducted using PubMed, The Cochrane Library, Scopus, and PEDro databases to identify studies evaluating the effects of physical prehabilitation program on exercise capacity, muscle strength, respiratory muscle function, postoperative complications, length of hospital stay, mortality, and health-related quality of life in patients with esophagogastric cancer awaiting surgery. Data from all studies meeting the inclusion criteria were extracted. The quality of each selected study was determined using the Downs and Black checklist.

Results

Seven studies with 645 participants were included. The preoperative exercise program consisted of respiratory training alone in three studies, a combination of aerobic and resistance training in two studies, and a combination of respiratory, aerobic, and resistance training in two studies. Training frequency ranged from three times a day to twice a week and each session lasted between 20 and 75 min. Four studies were of fair quality and three of good quality. Some studies reported improvements in maximal inspiratory pressure, inspiratory muscle endurance, postoperative (pulmonary) complications, and length of hospital stay in the preoperative exercise group compared to the control group.

Conclusion

This systematic review reports the current evidence for physical prehabilitation programs in patients with esophagogastric cancer awaiting surgery. However, due to the limited number of randomized controlled trials, the significant heterogeneity of exercise programs, and the questionable quality of the studies, higher quality randomized controlled trials are needed.

Esophagopericardial Fistula After Esophagectomy

Esophagectomy is the mainstay surgical treatment for esophageal carcinoma. The operation can be complicated by an anastomotic stricture, anastomotic leak, recurrent laryngeal nerve injury, conduit ischemia, and chylothorax. Rarely, esophagectomy can be complicated by fistula formation between the gastrointestinal tract and the nearby structures. We describe a case of esophagopericardial fistula after esophagectomy. A 50-year-old man presented to the emergency room with a chest pain of two-week duration associated with sweating, chills, and poor appetite. He was diagnosed with stage III esophageal adenocarcinoma four months ago. He had received neoadjuvant chemotherapy followed by distal esophagectomy, partial gastrectomy, and placement of a jejunostomy tube one month before presentation. Cardiovascular examination was significant for jugular venous distention and distant heart sounds. Chest CT angiography showed pneumomediastinum concerning for anastomotic leak. Esophagram finally confirmed an esophagopericardial fistula. A drain was placed into the pericardial space followed by emergent esophageal stent placement. Eventually, he underwent a cervical esophagostomy and placement of a jejunostomy tube. The patient was later discharged home in a stable condition. In conclusion, esophagopericardial fistula is a rare adverse event of esophagectomy. Esophageal stenting could be useful as a temporary or definite treatment.

Addressing the changing rehabilitation needs of patients undergoing thoracic surgery

The rehabilitation needs of individuals undergoing thoracic surgery are changing, especially as surgical management is increasingly being offered to patients who are at risk of developing functional limitations during and after hospital discharge. In the past rehabilitative management of these patients was frequently limited to specific respiratory physiotherapy interventions in the immediate postoperative setting with the aim to prevent postoperative pulmonary complications. In the past two decades, this focus has shifted toward pulmonary rehabilitation interventions that aim to improve functional status of individuals, both in the pre- and (longer-term) postoperative period. While there is increased interest in (p)rehabilitation interventions the majority of thoracic surgery patients are however currently on their own with respect to progression of their exercise and physical activity regimens after they have been discharged from hospital. There are also no formal guidelines supporting the referral of these patients to outpatient rehabilitation programs. The current evidence regarding rehabilitation interventions initiated before, during, and after the hospitalization period will be briefly reviewed with special focus on patients undergoing surgery for lung cancer treatment and patients undergoing lung transplantation. More research will be necessary in the coming years to modify or change clinical rehabilitation practice beyond the acute admission phase in patients undergoing thoracic surgery. Tele rehabilitation or web-based activity counseling programs might also be interesting emerging alternatives in the (long-term) postoperative rehabilitative treatment of these patients.

Efficacy of enhanced prehabilitation for patients with esophageal cancer undergoing esophagectomy

BACKGROUND

Several studies have demonstrated that prehabilitation helps reduce the incidence of postoperative complications. In this study, we investigated the safety and efficacy of enhanced prehabilitation (EP) in the hospital for patients with esophageal cancer.

METHODS

We retrospectively reviewed the data of 48 consecutive patients who underwent radical esophagectomy with gastric tube reconstruction between September 2015 and June 2019. EP program had been introduced in August 2017. In the EP group, patients received the EP program during hospitalization 7 days before surgery in addition to conventional perioperative rehabilitation. The EP program consisted of aerobic exercise and muscle strength training in the morning and afternoon. Operative outcomes were compared between patients who received EP (EP group; 23 patients) and patients who did not receive EP (control group; 25 patients).

RESULTS

The preoperative (EP group vs. control group, 492.9 ± 79.7 vs. 418.9 ± 71.8 m, p < 0.001) and postoperative (EP group vs. control group, 431.5 ± 80 vs. 378 ± 68.7 m, p < 0.001) 6-min walk distance was significantly higher in the EP group than in the control group. The respiratory complications rate was significantly lower in the EP group (4.3%) than in the control group (36%) (p = 0.007). The incidence of atelectasis was particularly significantly lower in the EP group (0%) than in the control group (24%) (p = 0.012).

CONCLUSIONS

EP was performed safely for patients before esophagectomy. EP improved the exercise tolerance of the patients before esophagectomy and might be useful in preventing respiratory complications.

Adding autogenic drainage to chest physiotherapy after upper abdominal surgery: effect on blood gases and pulmonary complications prevention. Randomized controlled trial

BACKGROUND

Hypoxemia and pulmonary complications are common after upper abdominal surgery (UAS).

OBJECTIVE

To examine whether inclusion of autogenic drainage (AD) in chest physiotherapy after UAS confers additional benefits in improving blood gases and reducing postoperative pulmonary complications (PPCs).

DESIGN AND SETTING

Randomized controlled study conducted at Kasr Al-Ainy teaching hospital, Egypt.

METHODS

A randomized controlled trial was conducted on 48 subjects undergoing elective UAS with high risk of developing PPCs. The study group received AD plus routine chest physiotherapy (deep diaphragmatic breathing, localized breathing and splinted coughing) and the control group received routine chest physiotherapy only. The outcomes included arterial blood gases measured at the first and seventh postoperative days, incidence of PPCs within the first seven days and length of hospital stay.

RESULTS

Baseline characteristics were similar between groups. In the AD group, SaO2, PaO2, PaCO2 and HCO3 significantly improved (P < 0.05) while in the physiotherapy group, only SaO2 and PaO2 significantly improved (P < 0.05). Nonetheless, significant differences in post-treatment SaO2 and PaO2 between the groups were observed. The overall incidence of PPCs was 16.66% (12.5% in the AD group and 20.8% in the physiotherapy group) (absolute risk reduction -8.3%; 95% confidence interval, CI, -13.5 to 29.6%), with no significant difference between the groups. The AD group had a significantly shorter hospital stay (P = 0.0001).

CONCLUSION

Adding AD to routine chest physiotherapy after UAS provided a favorable blood gas outcome and reduced the length of hospital stay. It tended to reduce the incidence of PPCs.

Cancer Rehabilitation and Palliative Care-Exploring the Synergies

With perpetual research, management refinement, and increasing survivorship, cancer care is steadily evolving into a chronic disease model. Rehabilitation physicians are quite accustomed to managing chronic conditions, yet, cancer rehabilitation remains unexplored. Palliative care physicians, along with rehabilitationists, are true generalists, who focus on the whole patient and their social context, in addition to the diseased organ system. This, together with palliative care's expertise in managing the panoply of troubling symptoms that beset patients with malignancy, makes them natural allies in the comprehensive management of this patient group from the moment of diagnosis. This article will explore the under-recognized and underused parallels and synergies between the two specialties as well as identifying potential challenges and areas for future growth.

Esophageal cancer surgery: review of complications and their management

Esophagectomy, even with the progress in surgical technique and perioperative management, is a highly specialized surgery, associated with a high rate of complications. Early recognition and adequate treatment should be a standard of care for the most common postoperative complications: anastomotic leakage, pneumonia, atrial fibrillation, chylothorax, and recurrent laryngeal nerve palsy. Recent progress in endoscopy with vacuum and stent placement, or in radiology with embolization, has changed the management of these complications. The success of nonoperative treatments should be frequently reassessed and reoperation must be proposed in case of failure. We have summarized the clinical signs, diagnostic process, and management of the frequent complications after esophagectomy for esophageal cancer.

The prognostic value of sarcopenia combined with hepatolithiasis in intrahepatic cholangiocarcinoma patients after surgery: A prospective cohort study

INTRODUCTION

Intrahepatic Cholangiocarcinoma (ICC) is the second most common primary liver cancer with dismal survival rates. This study aimed to explore the prognostic value of sarcopenia combine with hepatolithiasis in surgically treated ICC patients and develop a prognostic nomogram to help make clinical decisions.

MATERIALS AND METHODS

A prospective cohort study was conducted including patients who underwent hepatectomy for ICC between August 2012 and October 2019. The association between the sarcopenia combined with hepatolithiasis and survival, including overall survival (OS) and recurrence-free survival (RFS) was investigated using the Kaplan-Meier (K-M) method. Univariable and multivariable Cox regression analysis was performed to determine the independent prognostic factors and a nomogram establishment was undertaken based on the multivariable analysis.

RESULTS

A total of 121 ICC patients were included in the study. K-M analysis revealed that ICC patients with sarcopenia and hepatolithiasis have worse OS and RFS than those without sarcopenias and/or hepatolithiasis (p < 0.01). Multivariable analysis showed that age, serum CEA, hepatolithiasis, sarcopenia and diabetes were independent prognostic factors for OS(p < 0.05). Finally, a nomogram with good performance in survival prediction was established (C-index was 0.721; the area under the curve of OS was 0.837). The stratified analysis based on the nomogram disclosed that the median OS was 11.9 months in high-risk patients and 51.2 months in low-risk patients (p < 0.001).

CONCLUSIONS

ICC patients with sarcopenia and hepatolithiasis have worse OS and RFS. The nomogram we developed is a practical tool that can provide a more individualized risk assessment for surgically treated ICC patients.

Feasibility and Preliminary Effectiveness of a Tele-Prehabilitation Program in Esophagogastric Cancer Patients

Tele-rehabilitation provides better access to healthcare services and optimizes exercise adherence. However, its feasibility and effectiveness are unknown in the preoperative period in esophagogastric cancer patients. We aimed to assess the feasibility and the preliminary effects of a “tele-prehabilitation” program in esophagogastric cancer patients requiring surgery. Enrolled participants performed an internet-based tele-prehabilitation including aerobic, resistance and inspiratory muscle training over 2–4 weeks. The primary outcome was feasibility, measured in terms of recruitment, retention and attendance rates, adverse events and patient satisfaction. Secondary outcomes (functional exercise capacity, fatigue, quality of life, anxiety and depression) were assessed at baseline, presurgery, and 4 and 12 weeks postsurgery. Among the 24 eligible subjects, 23 were enrolled, 22 performed the intervention and 15 completed the study. Recruitment and retention rates were both 96%. Attendances to aerobic and resistance sessions and inspiratory muscle training were 77% and 68%, respectively. No adverse events occurred, and the satisfaction was excellent. After prehabilitation, participants significantly improved fatigue (p = 0.039), quality of life (p = 0.009), physical well-being (p = 0.034), emotional well-being (p = 0.005) and anxiety (p = 0.044). This study demonstrated the feasibility of a tele-prehabilitation in esophagogastric cancer patients undergoing surgery, with a high recruitment rate, retention rate and satisfaction, a good attendance to exercise sessions and no exercise-related adverse events.

The impact of preoperative sarcopenia on postoperative complications following esophagectomy for esophageal neoplasia: a systematic review and meta-analysis

Esophageal cancer is characterized by profound changes in body composition due to dysphagia and generalized cachexia. Sarcopenia or muscle wasting is a component of cachexia associated with poor postoperative performance status. The skeletal muscle index (SMI) calculated by computed tomography scans at the level of the third lumbar vertebra is an easily quantifiable and reproducible measure of sarcopenia. The aim of this meta-analysis is to investigate the impact of preoperative sarcopenia (low SMI) on postoperative complications after esophagectomy for neoplastic lesions. In this context, a comprehensive literature search was undertaken to identify studies reporting short-term postoperative outcomes in relation to their preoperative SMI values. Cumulative risk ratios (RR) and risk differences (RD) and their respective 95% confidence intervals (CIs) were calculated using a random-effect model. A total of 11 studies incorporating 1,979 total patients (964 patients with sarcopeniaversus 1,015 without sarcopenia) were included in the final analysis. The results demonstrated a significant increase in overall morbidity (RR 1.16, 95% CI 1.01-1.33), respiratory complications (RR 1.64, 95% CI 1.21-2.22) and anastomotic leaks (RR 1.39, 95% CI 1.10-1.76) in patients with sarcopenia. No statistically significant difference was noted in overall mortality (RD 0, 95% CI -0.02-0.02) or Clavien-Dindo grade III or greater complications (RR 1.17, 95% CI 0.96-1.42). The above results demonstrate the validity of the SMI as a predictive factor for post-esophagectomy complications. Although the risk associated with sarcopenia is not prohibitive for surgery, patients with low SMI require closer vigilance during their postoperative course due to the increased propensity for respiratory and anastomotic complications.

Prognostic Impact of Postoperative Complications following Salvage Esophagectomy for Esophageal Cancer after Definitive Chemoradiotherapy

BACKGROUND

Recent studies have reported that the occurrence of postoperative complications after esophagectomy for esophageal cancer has a negative impact on long-term survival. Although salvage esophagectomy is associated with higher rates of morbidity and mortality, the impact of postoperative complications on long-term survival following salvage esophagectomy has not been fully investigated.

METHODS

We retrospectively analyzed 73 patients with thoracic esophageal cancer who underwent salvage esophagectomy between January 1997 and December 2017 after definitive chemoradiotherapy. We investigated the clinical impact of postoperative complications on long-term survival after salvage esophagectomy.

RESULTS

Postoperative complications, pulmonary complications, and anastomotic leakage occurred in 34 (47%), 14 (13%), and 14 (19%) of the patients, respectively. Patients with complications had significantly poorer survival than patients who did not have complications (HR [hazard ratio], 2.06; p = 0.017), but there were no significant differences in overall survival between patients with and those without pulmonary complications or anastomotic leakage (HR, 1.48, p = 0.318, and HR, 1.37, p = 0.377, respectively). Multivariate analysis revealed that pathological T3-4 disease (HR, 4.63; p = 0.001), residual disease (HR, 5.09; p = 0.001), and postoperative complications (HR, 3.85; p = 0.001) were significant independent prognostic factors. In particular, the frequency of death from other diseases among patients with postoperative complications was nonsignificantly higher than among patients without postoperative complications (26 vs. 10%; p = 0.071).

CONCLUSION

The occurrence of complications leads to a poor prognosis for patients with esophageal cancer after salvage esophagectomy. Prevention of postoperative complications and long-term postoperative general supportive care might be important for improving patients' prognosis.

Preoperative six-minute walk distance as a predictor of postoperative complication in patients with esophageal cancer

Surgery for esophageal cancer is associated with high morbidity and mortality. Reduced pulmonary functions and exercise capacity are known as risk factors for complications after esophagectomy. The 6-minute walk distance (6MWD) measured by the 6-minute walk test (6MWT) is a simple field test that can be used to evaluate the functional exercise capacity of patients who undergo thoracic surgery. The aim of this study was to evaluate the association of the preoperative 6MWD with postoperative complications in patients with esophageal cancer. Records of a total of 111 patients who underwent thoracic surgery followed by postoperative rehabilitation from January 2013 to December 2015 were retrospectively reviewed. Data of patients who experienced Clavien-Dindo grade II or severer (grade ≥ II) complications were compared with those who experienced grade ≤I complications. The 6MWD was significantly correlated with age, serum albumin concentration, hemoglobin concentration, and hand grip strength. A total of 42 patients experienced grade ≥II. The 6MWD of patients with grade ≥ II complications was significantly shorter than that of those with grade ≤I complications. In receiver operating characteristic analysis, 6MWD ≤ 454 m was a threshold for predicting grade ≥II complications with 71.0% sensitivity and 54.8% specificity. The incidence of grade ≥II complications led to delayed ambulation and longer stays in hospital. In the multiple regression analysis, the preoperative risk factors for incidence of grade ≥II complications included lower levels of preoperative 6MWD and % of the predicted value of forced expiratory volume in 1 second. Our results indicate that the 6MWT is useful to assess preoperative physical status in patients with esophageal cancer.

Early Readmissions after Esophagectomy for Esophageal Adenocarcinoma: Does Facility Case-Volume Matter?

Increased esophagectomy procedures over the past four decades have correlated with the rise in incidence of esophageal adenocarcinoma. Despite advances in technology and procedural expertise, esophagectomy remains a high-risk surgical procedure. Higher volume facilities have more experience with esophagectomy and would be expected to have a lower incidence of surgical complications and attendant morbidity and mortality. By analyzing information from a nationwide United States hospital database, we sought to find out if there is a significant difference between facilities stratified by case volume, with regards to 30-day readmission after esophagectomy. The findings of this study indicated that even with a large applied differential, early readmissions did not differ significantly between high- and low-volume centers. Also, analyzed and discussed were any associated demographic and comorbidity factors as they relate to early readmissions after esophagectomy for esophageal adenocarcinoma across the country. This is the first study to specifically address these variables.

Development of a model predicting the risk of eight major postoperative complications after esophagectomy based on 10 826 cases in the Japan National Clinical Database

BACKGROUND

Esophagectomy is a highly invasive procedure with a high incidence of complications. The objectives of this study were to create risk prediction models for postoperative morbidity associated with esophagectomy and to test their performance using a population-based large database.

METHODS

A total of 10 862 patients who underwent esophagectomy between January 2011 and December 2012 derived from the Japanese national clinical database (NCD) were included. Based on the 148 preoperative clinical variables collected, risk prediction models for eight major postoperative morbidities were created using 80% (8715 patients) of the study population and validated using the remaining 20% (2147 patients) of the patients.

RESULTS

The mortality rate was 3.1% and postoperative morbidity was observed in 42.6% of the patients. The c-statistics of the eight risk models established by the training set were surgical site infection (0.564), anastomotic leakage (0.531), need for transfusion (0.636), blood loss >1000 mL (0.644), pneumonia (0.632), unplanned intubation (0.607), prolonged mechanical ventilation over 48 hours (0.614), and sepsis (0.618) in the validation analysis.

CONCLUSIONS

Risk prediction models for postoperative morbidity after esophagectomy using the population-based large database showed relatively fair performance. The current models may offer baseline information for risk stratification in clinical decision makings and help select more suitable surgical and nonsurgical treatment options and future clinical studies.

Multidisciplinary team management for prevention of pneumonia and long-term weight loss after esophagectomy: a single-center retrospective study

BACKGROUND

In April 2017, we launched the multidisciplinary Hamamatsu Perioperative Care Team (HOPE) for all surgical patients. We developed a reinforced intervention strategy, particularly for esophagectomy. We herein report the outcomes of the HOPE at 2 years after commencement.

METHODS

A total 125 patients underwent esophagectomy and gastric conduit reconstruction for esophageal or esophagogastric junction cancer between January 2014 and December 2018 at the Department of Surgery in Hamamatsu University School of Medicine. The patients were divided into the pre-HOPE group including 62 patients who underwent esophagectomy before the introduction of the HOPE and the HOPE group including 63 patients who underwent esophagectomy after the introduction of the HOPE. The outcomes of surgery were compared between the two groups.

RESULTS

There were no significant differences in the clinicopathological characteristics between the two groups. The incidence rates of atrial fibrillation and pneumonia were significantly lower in the HOPE group than in the pre-HOPE group (6% vs. 19%, p = 0.027 and 14% vs. 29%, p = 0.037, respectively). The estimated calorie doses at the time of discharge were approximately 750 and 1500 kcal/day in the pre-HOPE group and the HOPE group, respectively. The body weight loss was significantly less in the HOPE group than the pre-HOPE group at 1, 3, 6, and 12 months postoperatively than that before the surgery (p < 0.001).

CONCLUSIONS

The introduction of the multidisciplinary HOPE was associated with a significant reduction in the incidence of postoperative pneumonia and significantly less weight loss.

Esophageal Position Affects Short-Term Outcomes After Minimally Invasive Esophagectomy: A Retrospective Multicenter Study

BACKGROUND

Anatomical esophageal position may affect the short-term outcomes after minimally invasive esophagectomy (MIE). A previous single-institutional retrospective study suggested that the presence of a left-sided esophagus (LSE) made MIE more difficult and increased the incidence of postoperative complications.

METHODS

The current study was a multicenter retrospective study of 303 patients with esophageal cancer who underwent MIE at six esophageal cancer high-volume centers in Kyushu, Japan, between April 2011 and August 2016. The patients were divided into the LSE (66 patients) and non-LSE groups (237 patients) based on the esophageal position on computed tomography images obtained with the patients in the supine position.

RESULTS

Univariate analysis showed that patients with LSE were significantly older than those with non-LSE (69 ± 8 vs. 65 ± 9 years; P = 0.002), had a significantly greater incidence of cardiovascular comorbidity (65.2% vs. 47.7%; P = 0.013), and a significantly longer operating time (612 ± 112 vs. 579 ± 102 min; P = 0.025). Logistic regression analysis verified that LSE was an independent risk factor for the incidence of pneumonia (odds ratio 3.3, 95% confidence interval 1.254-8.695; P = 0.016).

CONCLUSIONS

The presence of a LSE can increase the procedural difficulty of MIE and the incidence of morbidity after MIE. Thus, careful attention must be paid to anatomical esophageal position before performing MIE.

Impact of Preoperative Skeletal Muscle Mass and Quality on the Survival of Elderly Patients After Curative Resection of Colorectal Cancer

OBJECTIVE

Skeletal muscle loss (sarcopenia) is a prognostic factor in patients undergoing gastrointestinal surgery. However, the influence of muscle quality on prognosis remains unclear. We retrospectively examined preoperative skeletal muscle quantity and quality impact on survival of elderly patients undergoing curative resection of colorectal cancer.

METHODS

We examined data from 142 patients aged ≥75 years who underwent curative resection of colorectal cancer between 2007 and 2012. We determined the size and quality of skeletal muscles, represented by the psoas muscle mass index (PMI) and intramuscular adipose tissue content (IMAC), respectively, using a preoperative computed tomography image. Overall survival (OS) and relapse-free survival (RFS) rates were determined according to values of PMI, IMAC, and other prognostic factors.

RESULTS

OS and RFS rates in patients with low PMI were lower than those in patients with normal PMI. The OS and RFS rates in patients with high IMAC were also lower than those in patients with normal IMAC. PMI and IMAC were independent prognostic factors for OS (hazard ratio [HR], 3.81, and 3.04, respectively); IMAC was an independent factor for RFS (hazard ratio [HR], 3.03).

CONCLUSION

Preoperative sarcopenia, indicating low quality and size of skeletal muscle, predicts mortality after curative resection of colorectal cancer in the elderly.

Clinical Importance of Sputum in the Respiratory Tract as a Predictive Marker of Postoperative Morbidity After Esophagectomy for Esophageal Cancer

BACKGROUND

Respiratory morbidity is common after esophagectomy and can be a major cause of surgery-related mortality. Thus, it is important to identify novel predictors that can preoperatively estimate the incidence of postoperative respiratory morbidity. Asymptomatic sputum in the respiratory tract is sometimes observed on preoperative computed tomography (CT). This study aimed to determine the clinical importance of sputum in the respiratory tract as a predictor of postoperative morbidity after esophagectomy for esophageal cancer.

PATIENTS AND METHODS

The study included 609 consecutive patients who underwent three-incisional esophagectomy for esophageal cancer between April 2005 and November 2018.

RESULTS

Among the patients, 76 (12.5%) had sputum in the respiratory tract on preoperative CT. This finding was significantly associated with older age, more extreme smoking habit, worse performance status, lower forced expiratory volume 1%, and more frequent pulmonary comorbidities. Additionally, the incidence of postoperative pneumonia was higher in these patients than in those without sputum (16 vs 8%, p = 0.028). Sputum in the main bronchus was associated with higher frequencies of morbidity of Clavien-Dindo classification (CDc) ≥ II (p = 0.019), severe morbidity of CDc ≥ IIIb (p = 0.058), pneumonia (p = 0.10), and pulmonary morbidity (p = 0.19) compared with the finding of sputum in the trachea alone. On multivariate analysis, sputum in the respiratory tract was an independent risk factor (hazard ratio, 2.07; 95% confidence interval, 1.019-4.207; p = 0.044) for postoperative pneumonia.

CONCLUSIONS

Sputum in the respiratory tract is a novel predictor of postesophagectomy pneumonia. Patients with sputum in the more distal respiratory tract might have high risk of postoperative morbidities.

Effectiveness and pulmonary complications of perioperative laryngeal mask airway used in elderly patients (POLMA-EP trial): study protocol for a randomized controlled trial

Background

With the increasing amount of geriatric surgery, it has become a great challenge for anesthesiologists to reduce the incidence of postoperative pulmonary complications (PPCs). The two most popular airway management methods, laryngeal mask airway (LMA) and endotracheal intubation (ETI), both have their unique advantages in specific clinical settings. For the purpose of helping clinicians make better decisions on airway management during geriatric surgery, we designed this multi-center clinical trial to compare the influence of LMA and ETI on PPCs.

Methods/design

In this multi-center, randomized, parallel clinical trial, a total of 6000 elderly patients, aged ≥ 70 years, with an American Society of Anesthesiologists classification level of 1–2 and a body mass index ≤ 35 kg/m², undergoing elective surgery will be enrolled and randomized into the LMA or the ETI group. Both groups will receive usual perioperative care except for the adoption of LMA/ETI. Primary outcomes are the occurrence of PPCs and patients’ perioperative mortality rates. Ease of intubation, anesthetics consumption, treatment for PPCs, duration of surgery, anesthesia recovery time and performance, time of PPC onset, postanesthesia care unit stay, intensive care unit admission and stay, in-hospital days, re-admission rates, hospitalization cost, and patients’ satisfactory scores will be secondary outcomes. Follow-up will be conducted through phone-call visits until 12 weeks after discharge.

Discussion

This trial will assess the possible benefits or disadvantages of perioperative LMA use in elderly patients compared with ETI regarding the occurrence of PPCs and clinical prognosis. We expect that this trial will also add to the current understanding of PPCs in geriatric populations and contribute to the international recommendations of geriatric surgery management.

Gastric ulceration causing thoracic spondylodiscitis: a first case of a rare complication post oesophagectomy

We report the case of an 84-year-old male, who presented with septicaemia, abdominal and back pain. The patient had a background of oesophageal carcinoma and had undergone previous oesophagectomy and gastric pull-up operation 10 years ago. A computerised topography scan demonstrated a probable gastro-vertebral communication with a destructive process at the T8/T9 vertebral level. Further evaluation with MRI clearly showed the tract between the two structures and confirmed the diagnosis of spondylodiscitis at the adjacent spinal level. The patient was resuscitated, treated with intravenous antibiotics and kept nil by mouth. A subsequent gastroscopy demonstrated an eroding gastric ulcer at the enteric opening of the tract between the tubal stomach and the spinal column. The diagnosis was discussed with the patient, his family and the surgical multidisciplinary team. Given the extent of disease and his multiple medical co-morbidities, the decision was made for conservative management and symptom control. This is the first case of a gastro-vertebral communication causing spondylodiscitis to be described in the literature.

The role of rehabilitation in patients undergoing oesophagectomy for cancer and pre-malignant disease: A qualitative exploration of the views of patients, carers and healthcare providers

OBJECTIVE

Oesophagectomy for cancer is associated with significant morbidity and mortality, and reduced quality of life. Structured rehabilitation potentially offers improved physical and psychological outcomes. We aimed to explore patient, carer and healthcare provider attitudes and preferences towards the role of rehabilitation.

METHODS

We interviewed 15 patients who had undergone an oesophagectomy, 10 carers and 13 healthcare providers about perceived impacts of treatment; preferred components of a rehabilitation program; barriers/enablers of support provision; and participation in rehabilitation programs. Data were analysed using framework analysis.

RESULTS

The overarching theme was "Getting back to normal." Diagnosis of disease signified a disruption to the normal trajectory of patients' lives and the post-treatment period was characterised as striving to return to normal. Patients and carers focused on rehabilitation needs post-treatment including dietary support, physiotherapy and healthcare provider support. Healthcare providers described rehabilitation as potentially beneficial from the pre-treatment phase and, along with carers, highlighted the importance of psychological support. Barriers included access to services, cost of service provision and appointment burden.

CONCLUSION

A need for rehabilitation services was identified by healthcare providers from the point of diagnosis, rather than only after surgery. Implications include improved service provision by healthcare institutions for patients undergoing oesophagectomy.

Clinical usefulness of a perioperative bacteriological culture to treat patients with postoperative pneumonia after esophagectomy

AIM

The aim of the present study was to examine the usefulness of a perioperative bacteriological culture in predicting the pathogenic bacteria responsible for postoperative pneumonia after esophagectomy.

METHODS

This study included 293 consecutive esophageal cancer patients who underwent esophagectomy with gastric conduit reconstruction. We compared the pathological bacteria that were detected in bacteriological cultures of sputum, mouthwash and gastric fluid on the second postoperative day with the pathogenic bacteria responsible for postoperative pneumonia.

RESULTS

Postoperative pneumonia occurred in 26 (8.8%) of the 293 patients. Enterobacter cloacae was detected most frequently in the perioperative bacteriological culture, followed by Enterococcus faecalis and Pseudomonas aeruginosa. Detection of each pathogenic bacterium in the perioperative bacteriological culture was not associated with the occurrence of pneumonia, excluding Pseudomonas aeruginosa. As the pathogens responsible for postoperative pneumonia, 32 bacteria were detected in 26 patients with postoperative pneumonia. Detection rate of the pathogenic bacteria responsible for postoperative pneumonia in a perioperative bacteriological culture was 43.8% in a sputum culture, 40.6% in a mouthwash culture and 65.6% in a gastric fluid culture. The detection rate of the pathogenic bacteria responsible for pneumonia was up to 78.1% in the combination of sputum and gastric fluid culture.

CONCLUSIONS

Although the perioperative bacteriological culture does not seem to be useful for predicting the occurrence of postoperative pneumonia, it is useful for predicting the pathogenic bacteria responsible for pneumonia in cases of postoperative pneumonia. The perioperative bacteriological culture helps us to select appropriate antibiotics to treat pneumonia after esophagectomy.

The Impact of Total Body Prehabilitation on Post-Operative Outcomes After Major Abdominal Surgery: A Systematic Review

BACKGROUND

Despite advances in perioperative care, post-operative clinical and functional outcomes after major abdominal surgery can be suboptimal. Prehabilitation programmes attempt to optimise a patient's preoperative condition to improve outcomes. Total body prehabilitation includes structured exercise, nutritional optimisation, psychological support and cessation of negative health behaviours. This systematic review aims to report on the current literature regarding the impact of total body prehabilitation prior to major abdominal surgery.

METHODS

Relevant studies published between January 2000 and July 2017 were identified using MEDLINE, EMBASE, AMED, CINAHL, PsychINFO, PubMed, and the Cochrane Database. All studies published in a peer-reviewed journal, assessing post-operative clinical and functional outcomes, following a prehabilitation programme prior to major abdominal surgery were included. Studies with less than ten patients, or a prehabilitation programme lasting less than 7 days were excluded.

RESULTS

Sixteen studies were included, incorporating 2591 patients, with 1255 undergoing a prehabilitation programme. The studies were very heterogeneous, with multiple surgical sub-specialties, prehabilitation techniques, and outcomes assessed. Post-operative complication rate was reduced in six gastrointestinal studies utilising either preoperative exercise, nutritional supplementation in malnourished patients or smoking cessation. Improved functional outcomes were observed following a multimodal prehabilitation programme. Compliance was variably measured across the studies (range 16-100%).

CONCLUSIONS

There is substantial heterogeneity in the prehabilitation programmes used prior to major abdominal surgery. A multimodal approach is likely to have better impact on functional outcomes compared to single modality; however, there is insufficient data either to identify the optimum programme, or to recommend routine clinical implementation.

The role of prehabilitation in frail surgical patients: A systematic review

INTRODUCTION

Increasing emphasis is being placed on the detection of frailty in the pre-operative setting given its association with surgical morbidity and mortality. Prehabilitation seeks to increase the physiological reserve of frail patients, attenuating the risk of irreversible functional decline following surgery.

AIM/HYPOTHESIS

This systematic review appraises the evidence available for prehabilitation in frail surgical patients. We proposed that exercise prehabilitation would especially benefit frail patients, with improvements in pre-operative functional capacity, and reductions in complications and length of hospital stay.

METHODS

A literature search was conducted in MEDLINE, PubMed and CINAHL databases. Studies were included if they consisted of a prehabilitation intervention in frail patients undergoing surgery and specified a frailty model/index. Eight studies were included for analysis, 2 of which are ongoing studies.

RESULTS

In 3 studies, prehabilitation consisted of an exercise intervention alone. There was a high feasibility of prehabilitation and a trend to improved pre-operative function, however, no evidence of improved post-operative functional recovery was there. In 2 studies, prehabilitation consisted of both exercise and nutritional interventions. Reductions in mortality and duration of hospital stay were reported, but the quality of evidence was judged to be very low. There was a lack of evidence of improved outcomes following pre-operative inspiratory muscle training in frail patients.

DISCUSSION

This systematic review focuses on prehabilitation in frail surgical patients and reports that evidence supporting any outcome is limited, despite high feasibility and acceptability. There is a need for large randomised controlled trials to better establish the effects of prehabilitation in frail patients.

Impact of postoperative complications on outcomes after oesophagectomy for cancer

BACKGROUND

To allocate healthcare resources optimally, complication-related quality initiatives should target complications that have the greatest overall impact on outcomes after surgery. The aim of this study was to identify the most clinically relevant complications after oesophagectomy for cancer in a nationwide cohort study.

METHODS

Consecutive patients who underwent oesophagectomy for cancer between January 2011 and December 2016 were identified from the Dutch Upper Gastrointestinal Cancer Audit. The adjusted population attributable fraction (PAF) was used to estimate the impact of specific postoperative complications on the clinical outcomes postoperative mortality, reoperation, prolonged hospital stay and readmission to hospital in the study population. The PAF represents the percentage reduction in the frequency of a given outcome (such as death) that would occur in a theoretical scenario where a specific complication (for example anastomotic leakage) was able to be prevented completely in the study population.

RESULTS

Some 4096 patients were analysed. Pulmonary complications and anastomotic leakage had the greatest overall impact on postoperative mortality (risk-adjusted PAF 44·1 and 30·4 per cent respectively), prolonged hospital stay (risk-adjusted PAF 31·4 and 30·9 per cent) and readmission to hospital (risk-adjusted PAF 7·3 and 14·7 per cent). Anastomotic leakage had the greatest impact on reoperation (risk-adjusted PAF 47·1 per cent). In contrast, the impact of other complications on these outcomes was relatively small.

CONCLUSION

Reducing the incidence of pulmonary complications and anastomotic leakage may have the greatest clinical impact on outcomes after oesophagectomy.

Effect of early mobilization on postoperative pulmonary complications in patients undergoing video-assisted thoracoscopic surgery on the esophagus

BACKGROUND

Esophagectomy performed via thoracotomy is associated with a high rate of postoperative pulmonary complications. Video-assisted thoracoscopic surgery at the esophagus (VATS-E) can reduce the rate of postoperative pulmonary complications. VATS-E is being increasingly implemented owing to its benefits. This procedure makes early patient mobilization possible, because there is minimal thoracic wall invasion, and thus, less postoperative pain. This study aimed to identify the efficacy of early mobilization in patients undergoing VATS-E.

METHODS

We retrospectively reviewed the patients who underwent VATS-E between November 2008 and October 2016. All the patients underwent preoperative physiotherapy and postoperative early mobilization for standard perioperative management. We examined the relation between early mobilization and the factors affecting postoperative pulmonary complications and the duration of physiotherapy with regard to the surgical outcome of VATS-E.

RESULTS

A total of 118 patients who underwent VATS-E were assessed. The incidence of postoperative pulmonary atelectasis decreased with early mobilization, and earlier mobilization was associated with a better decrease (P < 0.001). Multiple logistic regression analysis identified the percentage of volume capacity [odds ratio (OR) 0.96; 95% confidence interval (CI) 0.93-0.99] and initial walking (OR 1.82; 95% CI 1.40-2.48) as independent risk factors for postoperative pulmonary atelectasis. In addition, the presence or absence of atelectasis was found to reduce the necessary period of physiotherapy (P < 0.001).

CONCLUSION

Our results indicated that early mobilization reduces the incidence of postoperative pulmonary atelectasis, which may also contribute to early recovery in patients who undergo VATS-E.
